To all whom it may concern: I

Be it known that 1-, HENRY ERNEST PARRY TAYLOR, a citizen of the UnitedStates, residing at Seymour, county of New Haven, and State ofConnecticut, have invented certain new and useful Improvements in Wire-Drawing Machines,' of which the following is a specification.

This invention relates to wire drawing machines and it consists in thenovel construction and arrangement of its parts as hereinafter shown anddescribed.

Wire drawing machines as heretofore used have been of relativelycomplicated construction, which complications have been detrimental tothe character of work performed by the machines and have been a sourceof much expense for installation and maintenance. v

Among the objectionable features found in such machines may bementioned, first: complicated lever mechanisms for operating clutchmembers; second: unsatisfactory means for transmitting movement to themovable parts of the machines, whichimeans lack suitable and simplemeans for-holdin the wire reel in position; and third: insu ficientprovision for the proper adjustment properly presented to the wireblock.

The object of this invention is to provide a machine cf the characterindicated which is of durable construction and simple arrangement ofparts and which is adapted to be used for drawing wire of comparativelyminute transyerse-dimension's up to rods of five-eighths of an inch indiameter or thereabout." p K My machine consists primarily of a rotating shaft from which a wire block is suspended and a simple anddurable clutch mechanism for transmitting movement to the said'shaft;'An effective means is provided for transmitting movement toa worm shaftthrough which motion is initially transmitted to the 'movable parts ofthe machine. A wire reel of special construction 7 is provided. A'shiftable plate is mounted upon the bed-plate of the machine andsupports the wire reel above mentioned and a die holder in a manner'aswill be herein after explained.

I, which ismounted upon the wire may be by horizontal pul Theaccompanying drawings illustrate my 5 improved invention, in whichsimilar reference characters indicate like parts.

Figure 1 1s a front elevation of the machine. Fig. 2 is a side elevationof the maother. Fig. 4 is a horizontal sectional View of the machinetaken on the line t4 of Fig. 2. Fig. 5 is a horizontal sectional viewtaken on the line 5-5 of hi 2. Fig. 6 is a horizontal sectional view 0 aportionof a wire block used upon the machine. Fig. 7'

is a vertical sectional View of a wire clamping device mounted upon thesaid wire block, and Fig. 8 is a vertical sectional view of a shi ftablestandard mounted upon the machine'and carrying a wire reel and a dieholder. j I

' The machine is provided with a bed-plate base 2. The standard '3 isfixedto the bed-plate 1 and the horizontally disposed shaft 4 isjournaled for rotation in the upper portion of the standard '3. Thepower pulleys 5, 5, are attached to the opposite ends of the shaft 4:and the worm 6.1s. attached to the intermediate portion of theshaft 4and is housed within the dome 7 located at the upper end of the standard3. y The provision of a pulley on either end of the shaft 4 isparticularly designed to increase the steadiness of operation of themachine. As drive belts runnin over ulleys will generally exert apartial horizontal pull upon the machine; it wil be evident that .bysecuring a drive pulley 5 to each end of shaft 4, swinging movement ofthe shaft in its bearin s which would be caused l on one end of theshaft, will. be prevented b horizontal pull in the same direction on te'other end. Further it will be evident that when strain is exerted uponshaft 11, and transmitted through worm wheel 9, to oneside of vworm 6,said strain will cause swinging movement of shaft 4, and it will beevident that this swinging movement will be prevented by the doublepulley arrangement. It will there fore be seen that the double pulleyarrangeloo 1 rotates with the same.

ment will equalize or balance the strain upon the machine intransmlssion of power to overcome the strain upon shaft 11.

The sleeve 8 is journaled for rotation in the upper portion of thestandard 3 and the worm wheel 9 is fixed to said sleeve. Said wheel 9 ishoused within the casing 10 which communicates with the dome 7 and isalso supported at the upper end of the standard 3. The wheel 9 mesheswith the worm 6.

The shaft 11 is journaled in the sleeve 8 the trunnions 18 and is fixedto a shaft 20- which in turn is journaled in the standard 3. The arm 21is fixed to the shaft 20 and is rovided with an adjustable weight22. Thelink 23 is pivotally connected at its upper end to the arm 21 and ispivotally connected at its lower end to the lever 24 which in turn isjournaled to the side of the standard 3.

' The wire block 25 is suspended at the lower one end a die receivin endof the shaft 11. Said block is sub stantially conical in configurationand has in its side a recess 26, in which a wire clamping device 27 ispivotally mounted. The said wire clamping device is provided with themovable jaws 28 between which the end of the wire about to be drawn isconfined.

The plate 29 is mounted upon the bedplate, 1 and has at its oppositesides elongated perforations 30 through which the bolts 31 pass andsecure the said plate to the bed-plate. The plate 29 is rovided at itsouter edge with a depending ug 32 which is provided with a set-screw 33adapted to operate against the edge of the bed-plate 1 and which isadapted, when turned, to move the plate 29 to or from the wire block 25.The plate 29 is provided upon its upper side with the guides 34 whichreceive the block '35. The yoke 36 is pivotall mounted upon the block 35and is adapte to swing horizontally.

The die I older 37 is pivoted in said yoke and is adapted to swinvertically. The block 35 may be adjuste longitudinally in the guides andthe die holder 37 has at socket 38 in which is located a detachab e die39. The die holder 37 is channeled out or troughed throu hout its entirelength in a, plane occupie by the opening in the die 39, so as not tointerfere with the feeding of the wire to the said die. The die holder37 is provided at its end opposite to that to which the die is appliedwith a downwardly inclined shank 40 upon which is adjustably mounted acounterbalance weight 41. During the rotation of the wire block the dieholder tends to move vertically along the face of the wire block. Thistendency varies at different parts of the operation and theadjustableweight is provided to maintain the die-holder in correct position underdifierent strains.

The standard 42 is fixed at its lower end to the guides 34 and isshiftable with the plate 29;. consequently the said standard may movetoward and from the wire block 25. The block 35 and its attachments maybe shifted laterally with relation to the said wire block.These/adjustments are desirable in drawing wire of different diameters.The reel 43 is mounted upon the standard 42 and is adapted to be passedthrough a coil of wire indicated by the dotted lines 44 in Fig. 1. Thesaid reel is provided at its ends with the plates 45 which'- areprovided at their sides remote from the wire block 25 with thejo'urnaled friction rollers 46 which also. pass transversely through thewire, roll and tend to reduce the friction as the wire is unwound fromthe said roll.

The operation of my machine is as follows: The shaft 4 is rotated bymeans of belts (not shown) which pass around the pulley wheels 5--5Inasmuch as the shaft 4 carries the worm 6 which is in mesh with theworm wheel 9 and the ower is applied simultaneously to both end of theshaft 4 the tendency of the said shaft to have swinging movement ismaterially reduced or ensiderable degree the wear and friction of theshaft in its bearings, and preventing wear and friction upon the worm 6and worm wheel 9. As the worm wheel 9 is rotated as above described, itcarries with it the sleeve 8 and the clutch member 13.

When it is desired to rotate the shaft 11 thetweenthe clamping jaws 28of the ivoted block 27. Therefore, as the saidb ock 27 is carried aroundwith the block 25 the wire is drawn from the reel 43 through the die 39and is wound upon the wire block 25. At the end of the o eration ofwinding the wire upon the bloc 25, and when the end of the wire 44passes through the die tirely avoided, thereby reducing to a con- As thelast said simple and durable construction is provided for drawing wireand that the parts are so arranged as to reduce friction and incidentalwear and tear to a minimum and the parts may be readily adjustedrelatively for drawing wire of different transverse dimensions. Havingdescribed my invention, what I claim as new and desire to secure byLetters Patent i's a T 1. In a machine of the character described,
